Base64 Encoder / Decoder
Easily convert text to Base64 encoding or decode Base64 back to text.
What is Base64 Encoding?
Base64 is a group of binary-to-text encoding schemes that represent binary data in an ASCII string format by translating it into a radix-64 representation. The term Base64 originates from a specific MIME content transfer encoding.
Base64 encoding schemes are commonly used when there is a need to encode binary data that needs to be stored and transferred over media that are designed to deal with textual data. This ensures that the data remains intact without modification during transport.
Common Uses for Base64
- Email Attachments: MIME uses Base64 to encode binary files like images or documents so they can be sent as text over SMTP.
- Data URIs: Web developers often use Base64 to embed small images directly into HTML or CSS files, reducing HTTP requests.
- API Authentication: Basic Authentication in HTTP uses Base64 to encode the username and password.
- Storing Complex Data: Sometimes complex data structures are encoded to Base64 to be safely stored in databases or cookies.
Important Note on Security
It is crucial to understand that Base64 is not encryption. It is merely an encoding format. Anyone with access to the Base64 string can easily decode it back to its original form. Never use Base64 to hide sensitive information like passwords or personal data without proper encryption.
